Curse of the Crimson Altar (aka The Crimson Cult) (DVD)

When his brother disappears, Robert Manning pays a visit to the remote country house he was last heard from. While his host is outwardly welcoming - and his niece more demonstrably so - Manning detects a feeling of menace in the air with the legend of Lavinia Morley, Black Witch of Greymarsh, hanging over everything.
